The magneto unit, whereon the dynamo unit is superimposed, is illustrated by itself in Figs. 7 to 10. The last figure illustrates the casing for the magneto, This casing is cast in two parts, the body a and front end wall a of aluminum, or of some other nonscrew 1 magnetic metal. in casting the body a, of the casing, the pole-shoes 14- are embedded therein so as to have their outer surfaces i'iush with the recessed side walls as shown in 10. The of the horizontally arpermanent magnet 16 are fitted into the recesses 15, formed in the side walls of the body a of the casing as explained, and the pole-shoes 14 are secured thereto by the s as shown in Fig. 7, illustrating the cor xpie c magneto unit in a perspective view.

Also the top and bottom plates of the magneto casing and the front wall a are suitably shaped exteriorly, and the interior of the body of the casing is turned to fit the rotatory part of the magneto. The front end wall of is extended upward, and shaped for mounting the rotatory part of the distributor therein. The lower portion of the front end wall a? is fitted upon the body a: of the magneto casing and is secured thereto by screws 11". Thus, the armature of the and the collector ring 26, may be se, i into the interior of the casing o when the 'nachine is being assembled, for which 1 purit-ose also the front and rear end walls or the casing are centrally perforated to ad mit passing therethre-ugh of the armature shaft The rear end wall may be supplemented by a plate a) see Fig. 10) to facilit the mounting of the circuit breaker on ie end of the armature shaft.

The apex of the magnet 16 is perforated, and the shaft 18 of the armature of the magnote is extended therethrough for a distance sufficient to have a gear keyed thereto, or other means, for driving the magneto from the shaft of the engin The washer 19 and nut 20, threaded onto the end of the'sha-ft 18, serve to secure thereto toe above-n'ientioned driving gear not shown in the drawing). The gear 21 is keyed to the armature shaft 18 inside of the arch of the magnet 16, and iesh'es with the distribnter gear 22, secured. to the sleeve 9 -5, fixed to the shaft 24, whereontne rotatory part of the distribut r is mounted.

The formation of the upper, or top side of thecasine' a is illustrated in Figs. 8 and 10. The pins 2'? set therein, and. the pins 28,

in the to) of the extension of the front tall serve on the casing of the dy unit ding bores 27 and '1 of the pins the non-magmatic I ing containing the dynamo o in the top side of the magneto casing are made to facilitate inspection of the armature wiring, etc., and the plate 79, set thereon and fastened by the screw 72 is provided to close these openings. The spring 31 shown in Figs. 8 and 10, laid within the recessed part of the top plate of the magneto casing serves for holding the stationary part (Z of the dis tributer against the rotatory part as shown in-Fig. 7, when the dynamo unit is removed. 7 5

The casing of the dynamo unit is illustrated in Figs. 6, 11 and 12. It is made up of four parts, the bottom plate 1), side walls and top, 6 composing the dome shaped central body of the casing, the front wall 71 and the rear wall If, supplemented by the part b, joining it with the bottom plate 7), to complete the inclosure within of'the C0111: ponent parts of the dynamo and. of its accessorie. The front wall 5 forms an arched extension of the upper part of the domeshaped central body of the casing, and overtops the stationary part d of the distributor and the extension a of the front wall of the magneto casing. It secured to the central body of the dynamo ea ng; by the screw 37 (see l 1 :5. 5 and 5) joining it to the arched top of the central body 6, and by the screws 38 (see Fig. 11), joining it to the bottom plate I) of the dynamo casing. The front wall 72 is centrally perforated the installation therein of a ball bearing for one end of the armature shaft 4C1 of the dynan'io, a corresponding bearing being provided in the rear wall 6" for the other end of the said shaft. The gear 12 is fixed on the end of this shaft, projecting beyond the front wall 72 of the dynamo caring. This gear 42 meshes with, and is driven by, the distributer gear 22, whereby the armature of the dyname is driven.

The bores 28 in the front wall If correspond in their positions to the positions of the pins 28, set in the extension ((1 of the front wall of the magneto casing him 10) and the bores 27 in the bottom plate are situated ,correspondingly to the positions of the pins 27 set in the top of the casing of the magneto unit, When the cas is set upon the casing housing, the magneto, the pins 27 and 28 enter into the bores 27, and 28", thus fixing the units in their relative positions to each other. The screw-threaded bore 32 in the side Walls of the magnet. easing are provided r aliixing th to, by the screws 33, of the hands 1, whereby the dynamo unit is secured to the magneto unit. The ends the bands 3%. are joined together by the bolt 35, passing through the bores in 125 the enlarged central portions of the studs 36, inserted in the folds of the said bands,

To protect the electrical con-n ta, it is desirabl ply over the arc front wall 6 of the dynamo casing the leather lined metallic strip 721. The spring 8 holds the strip in in its place and affords a ready access to the connections of the dynamo when an inspection thereof is required.

The statioi'lary part (Z' of the distributor, the part of the machine requiring most frequently to be inspected, is removable in $0230, being slid in, into the space (see Figs. and 6) between the trains of the rotatory part (.Z of the distributer, mounted in the extension oi. the front wall a of the magneto casing,

and the front wall b of the dynamo casing. The spring 39, tired in the lower portionof the front wall 6? is provided to engage the stationary part (l' of the distributor, when thus set in its place, the spring 39 being set to press it against the flt'tll'le of the rotatory part d. When the dynamo is removed from the machine, the soring 31, turnably secured to the top of the magneto casing (see Figs. 8 and 10) is set up as shown in Fig. 7, to perform this function.

The gears 21, 22 and 42, are shown in front view in Fig. 5, and in a sectional view in Fig. 6. To enable the distributor gear to be utilized as a transmission gear for the driving of the dynamo, the relative size of the gears 21 and 22 is determined to effect the driving of the rotatory part of the distributor at a speed correctly proportionate to-the speed of the magneto and according to the number of cylinders in the engine, and then the' 'size of the gear 42 is determined to drive the dynamo at the requisite speed to generate lighting current of voltage amply sufficientfor the purpose.
